The Automatic Transmission is a combination of a 3-e,ement torque convefter and triple-shaft electfonically controlled
automatic transmission which provides 4 speeds forward and 1 speed reverse. The entire unit is positioned in line with
the engine.
Torque Converter, Gears and Clutches
The torque converter consists of a pump, turbine and stator assembly in a single unit, The torque converter is connected
to the engine crankshaft so they turn together as a unit as the engine turns. Around the outside of the torque converter
is a ring gear which meshes with the starter pinion when the engine is being staned. The entire torque converter assem-
bly serves as a flywheel while transmitting power to the transmission mainshaft.
The transmission has three parallel shafts, the mainshaft. countershaft and sub-shaft. The mainshatt is in line with the
engine crankshaft.
The mainshaft includes the clutches for 1 st, and 2ndl4th, and gears for 3rd. 2nd, 4th, reverse and l st (3rd gear is in-
tegral with the mainshaft, while reverse gear is integral with the 4th gear).
The countershaft includes the 3rd clutch and gears Ior 3rd, 2nd,4th, reverse, lst and parking. Reverse and 4th gears
can be locked to the countershaft at its center, providing 4th gear or reverse, depending on which way the selector is moved.
The sub-shaft includes the lst-hold clutch and gears for 1st and 4th
The gears on the mainshait are in constant mesh with those on the countershaft and sub-shaft. When certain combina-
tions of gears in the transmission are engaged by the clutches, power is transmitted from the mainshaft to the counter-
shaft via the sub-shatt to provide @, E, tr. tr and @ position.
Electronic Control
The electronic control system consists of the Transmission Control Module {TCM), sensors, and 4 solenoid valves. Shift-
ing and lock-up are electronically controlled for comfortable driving under all conditions.
The TCM is located below the dashboard, behind the left side kick panel on the driver's side.
Hydraulic Control
The valve bodies include the main valve body, secondary valve body, regulator valve body. servo body, and lock-up valve
body throuqh the respective separator plates.
They are bolted on the torque converter housing.
The main valve body contains the manual valve, 1-2 shift valve, 2-3 shift valve, Clutch Pressure Cont.ol (CPC) valve,
4th exhaust valve, relief valve, and oil pump gears.
The secondary valve body contains the 4-3 kick-down valve,3-2 kick-down valve,2-3 orifice cont.ol valve, 3-4 shitt
valve, orifice control valve. modulator valve, and servo control valve
The regulator valve body contains the pressure regulator valve. lock-up control valve, torque converter check valve, and
cooler check valve.
The servo bodv contains the servo valve which is integrated with the reverse shift fork, throttle valve B, and accumulators.
The lock-ug valve bodv contains the lock-up shift valve and lock-up timing B valve. and is bolted on the secondary valve
body.
Fluid from the regulator passes through the manual valve to the various control valves.
Shitt Control Mochanism
Input to the TCM i.om various sensors located throughout the car determines which shift control solenoid valve should
be activated.
Activating a shift control solenoid valve changes modulator pressure, causing a shift valve to move. This pressurizes
a line to one of the clutches. engaging that clutch and its corresponding gear.
Lock-up Mechanism
In @ position. in 2nd, 3rd and 4th, and E position in 3rd, pressurized tluid can be drained from the back of the tor-
que converter through an oil passage, causing the lock-up piston to be held against the torque converter cover. As this
takes Dlace, the mainshaft rotates at the same speed as the engine crankshatt. Together with hydraulic control, the TCM
optimizes the timing ol the lock-up mechanism.
The lock-up valves control the range of lock-up according to lock-up control solenoid valves A and B, and throttle valve B
When lock-up control solenoid valves A and B activate, modulator pressure changes. Lock-up control solenoid valves
A and B are mounted on the torque converter housing, and are controlled by the TCM.
(cont'd)

In E position in 2nd, 3rd and 4th, and @ position in 3rd, pressurized fluid is drained from the back of the torque con-
verter through an oil passage, causing the lock-up piston to be held against the torque converter cover. As this takes
place, the mainshaft rotates at the same speed as the engine crankshaft. Together with hydraulic control, the TCM op-
timized the timing ot the lock-up system. Under certain conditions, the lock-up clutch is applied during deceleration, in
3rd and 4th sDeed.
The lock-up system controls the range of lock-up according to lock-up control solenoid valves A and B, and throttle valve B.
When lock-up control solenoid valves A and B activate. modulator pressure changes. Lock-up control solenoid valves
A and B are mounted on the torque converter housing, and are controlled by the TCM.

When used, "left" or " tight" indicates direction on the tlowchart.

S!@ ro prevent iniury to tace and eyes, always
wear safety glas$es or a tace shield when using the trans-
mission flusher.
NOTE: This procedure should be performed before rein-
stalling the transmission.
1. Check tool and hoses for wear or cracks before
using.
lf wear or cracks are found, replace the hoses be-
fore using.
2. Using the measuring cup, tillthe tank with 21 ounces
{approximately 213 lulll of biodegradable tlushing
fluid (J35944-20). Do not substitute with any other
fluid.
Follow rhe handling procedure on the fluid container.
Secure the tlusher filler cap and pressurize the tank
with compressed air to between 550-829 kPa(5.6-8.45 kgt/cm,, 80- 120 psi),
NOTE: The air line should be equipped with a water
trap to ensure a dry air system.
Hang the tool under the vehicle.
Attach the discharge hose of the tank to the return
line of the transmission cooler using a clamp.
Connect the drain hose to the inlet line of the trans-
mission cooler using a clamp. Securely clamp the op-posite end of the drain hose to a bucket or floor drain.

8. Turn on the flusher water valve so water will tlow
through the oil cooler for 1O seconds. lf water does
not flow through the oil cooler it is completely
plugged, cannot be flushed, and must be replaced.
9. Depress the trigger to mix the tlushing lluid into the
water tlow. Use the wire clip to hold the trigger
oown.
10. While flushing with the water and flushing fluid for
2 minutes. turn the air valve on for 5 seconds every
15-20 seconds to create a surging action.
AIR PRESSURE:

1 1. Turn the water valve off. Release the trigger, then
reverse the hoses to the cooler so you can flush in
the opposite direction. Repeat steps 8 through 1O.
12. Release the trigger and allow water only to rinse the
cooler with water for one minute.
13. Turn the water valve off and turn off the water
supply.
14. Turn the air valve on to dry the system out with air
for two full minutes or until no moisture is visible
leaving the drain hose.
CAUTION: Residual moisture in the oil cooler 01
pipes can damage the transmission.
